ABSTRACT:
A pushbutton tuner arm mechanism features a lockable setting plate rotatably mounted on an arm reciprocatingly actuated by a pushbutton, the setting plate having an extension configured to engage a V-shaped tuning notch in a memory slide. A locking spring affixed to the arm peripherally engages portions of the setting plate to hold the arm in a chosen position, the locking force being releasable upon extraction of the pushbutton. An arcuate boss integral with the setting plate is configured to engage portions of a generally V-shaped cut in the arm to provide positive play-free locking of the setting arm in position.
